exporter.
In the Geometry visitor, use getNodePath to check if the Geometry node
is root instead of getNumParents.
Reset the state inside buildFaces to prevent duplication when a
Group is inside of Group.
I have found that certain image editing programs export DDS images with both the DDPF_FOURCC and DDPF_RGB pixel format flags. The DDS loader will give preference to the DDPF_RGB flag and try to deduce the format from the RGB bit mask values instead of using the more reliable FOURCC flag. This causes some images to not load, even though the FOURCC flag is supported. I've modified the loader so that it checks for the DDPF_FOURCC flag first, then falls back on deducing the format from the RGB bit masks.
The fix to allow the export of orphaned Geometry nodes accidentally
duplicated those geometry nodes in 'normal' scene trees. This commit
refactors the code to rely on the visitor to traverse the Geometry as
opposed to traversing the Geometry in the Geode visit and the Geometry
visit.
The gif loader was incorrectly setting pixels as transparent in certain animated gifs. It was ignoring the disposal method value in the extension block and always overwriting the alpha value in each frame. It is common for some animated gifs to set the disposal method so that the previous alpha value is retained. This patch modifies the loader to respect the disposal method flag.
I've made a change to osgDB::OutputStream::writeArrayImplementation so that it writes the array data in a single write operation for binary files. This significantly speeds up writing out osgb files for large data sets (e.g. point clouds). osgDB::InputStream already performs a similar optimization when reading array data from binary files.
Setting the reference time greater than the duration of a gif would cause a crash. Also, the current reference time is not immediately updated when manually setting the reference time.
I was getting a black image when enabling hardware mipmap generation on cubemaps. I believe the problem is that the base Texture class is hard coding GL_TEXTURE_2D when enabling mipmap generation, instead of using the target type from the derived class.
